dc.description.abstract | This thesis presents a determination of the Cabibbo-Kobayashi-Maskawa (CKM) matrix element magnitude |Vcb| and form-factor parameters of B̄0 → D*+ℓ−ν̄ℓ decays, where ℓ = e, μ. We conduct our analysis using Belle II data collected from 2019 to 2021, corresponding to an integrated luminosity of 189fb−1. In the Belle II experiment, electrons and positrons collide with a center of mass energy 10.58 GeV, which corresponds to the Υ(4S) mass. Subsequently, more than 96% of Υ(4S) mesons decay to BB̄. We reconstruct signal B̄0 → D*+ℓ−ν̄ℓ decays, followed by D*+ → D0π+ and D0 → K−π+ decays, without explicitly reconstructing the accompanying B meson produced in the Υ(4S) decay. | en |
